  Issues with area lights and specular highlights

I've been working on an include file that renders simple lens flares using 
POV's specular highlight system and I've encountered a problem: POV only 
uses area light attributes for the shadows of objects and not the diffuse 
or specular components. I am aware that this is documented in the help file 
but it can make many effects not work properly. I'm posting some images to 
p.b.s-f showing the problem. If there's no other way to address this, I'll 
consider adding a new keyword to my patch.
